The She DRIVES Act directs the Secretary of Transportation to update the Federal Motor Vehicle Safety Standards test devices and New Car Assessment Program (NCAP) testing procedures to include specific adult-male and adult-female test devices for frontal and side impacts. The bill names THOR frontal dummies (50th-percentile male and 5th-percentile female) and Worldwide Harmonized Side Impact Dummies (50th-percentile male and 5th-percentile female), requires NHTSA to set injury criteria based on real-world injuries, and mandates that female dummies be used in all front seating positions currently tested with male dummies.
Beyond the device mandates, the Act imposes concrete deadlines for notices of proposed rulemaking and final rules, orders updates to NCAP test procedures tied to those rules, and requires a roadmap report to Congress on other testing devices and international harmonization. For compliance officers, vehicle engineers, safety labs, and regulators, the bill creates short statutory timetables and an explicit Congressional reporting requirement that could accelerate changes to vehicle design, testing fleets, and certification workflows.
At a Glance
What It Does
The bill mandates specific crash test dummies (THOR 50M and THOR 05F for frontal; WHSID 50M and WHSID 05F for side), requires NHTSA to update injury criteria and testing procedures, and forces NCAP to adopt the new devices. It also orders a one-year roadmap report and a five-year follow-up to Congress on additional devices and international comparators.
Who It Affects
Automakers and suppliers who design restraint systems and occupant protection, independent and in-house crash test labs that operate compliance dummies, NHTSA and NCAP program staff, and dummy manufacturers/suppliers. State regulators and safety advocacy groups will also see downstream NCAP rating changes.
Why It Matters
The measure legally commits the United States to test for female injury risk at parity with males and pushes faster regulatory action and potential international harmonization—issues that can change vehicle design priorities, certification test matrices, and consumer-facing safety scores.

What This Bill Actually Does
The Act directs immediate regulatory changes and creates parallel administrative tracks for frontal and side-impact testing. For frontal impacts it requires the regulatory text for the named THOR dummies to be added to parts 571 and 572 within 15 days; it then forces NHTSA to complete an NPRM for the 5th-percentile female THOR within 60 days and a final rule within 120 days, while requiring the 50th-percentile male THOR final rule within 180 days.
For side impacts the bill gives NHTSA more runway: regulatory text must be revised within 18 months and the agency must publish a proposed rule within two years and a final rule within 30 months. Those schedules are statutory deadlines, not discretionary targets.
For each mandated final rule the agency must update injury criteria—head, neck, chest, abdomen, pelvis, upper leg and (where applicable) lower leg—’based on real world injuries and the greatest potential to increase safety.’ The Act also requires that adult female dummies be used in all front seating positions that, as of enactment, are tested with adult male dummies, which expands the seating positions covered by female-specific testing rather than limiting female dummies to a single seat or optional tests.The bill ties NCAP to these rulemakings by requiring NHTSA to promulgate final decision notices updating NCAP procedures to use the new devices. The timing of those NCAP decisions is coupled to the rule issuance schedule, with an explicit caveat that NHTSA should avoid delaying required safety-standard final rules by issuing NCAP decisions concurrently only when doing so will not slow the rulemaking timetable.Separately, the Act orders a 'testing devices roadmap': an initial report within one year identifying timelines to add other researched dummies, cataloguing more-advanced devices used abroad, and describing whether and how NHTSA can adopt foreign devices (for example EU NCAP dummies).
A five-year follow-up must report progress on those timelines and any newly observed foreign devices that exceed currently required or researched devices. Finally, a savings clause preserves NHTSA’s authority to update testing devices through other proceedings beyond those the Act mandates.
The Five Things You Need to Know
Within 15 days of enactment NHTSA must revise CFR parts 571 and 572 to list THOR-50M and THOR-05F for frontal testing.
NHTSA must publish an NPRM for the THOR-05F within 60 days and issue a final rule for it within 120 days; a final rule for THOR-50M is required within 180 days.
For side impacts the bill requires insertion of WHSID 50th- and 5th-percentile dummies into the regs within 18 months, an NPRM within 2 years, and a final rule within 30 months.
Each final rule must establish or update specific injury criteria (head, neck, chest, abdomen, pelvis, upper leg, and where noted lower leg) based on real-world injuries and must require female dummies in all front seating positions already tested with male dummies.
The Secretary must submit a testing-devices roadmap to two Congressional committees within 1 year and a follow-up report after 5 years identifying timelines, international comparators, and whether U.S. regs can adopt advanced foreign devices.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Establishes the Act’s public name: the She Develops Regulations In Vehicle Equality and Safety Act (She DRIVES Act). This is a formal naming provision with no operational effect but signals the bill's policy focus on vehicle safety equity.
Definitions
Defines key terms used throughout the Act: 'crashworthiness' by reference to 49 U.S.C. 32301, 'Secretary' as DOT Secretary, and 'testing device' by reference to part 572 of title 49 CFR. These cross-references anchor the statute to existing federal safety standard definitions and to the specific regulatory locus where test devices are codified.
Mandate for frontal THOR dummies and rulemaking deadlines
Requires immediate regulatory insertion of THOR-50M and THOR-05F into parts 571/572 and sets tight statutory deadlines for NHTSA to complete rulemakings: a 60-day NPRM and 120-day final rule for the female THOR, and a 180-day final rule for the male THOR. The section also directs NHTSA to update injury criteria tied to those dummies and to require female dummies for all front seating positions currently tested with male dummies. Practically, this forces agencies and industry to accelerate test-fleet purchases, calibration, and validation work on very short timelines.
WHSID dummies for side impacts and phased rule schedule
Directs NHTSA to revise parts 571/572 to include 50th- and 5th-percentile Worldwide Harmonized Side Impact Dummies within 18 months, then to issue an NPRM within two years and a final rule within 30 months. The Secretary must update injury criteria for side impact dummies and require female dummies to be used in the same front seating positions tested for males. The longer timetable acknowledges additional development work needed for harmonized side-impact devices but still creates statutory pacing for adoption.
NCAP must adopt new devices; timing linked to safety-standard rules
Requires NHTSA to promulgate final decision notices to update NCAP testing procedures to use the newly required devices. The statute ties NCAP update timing to the issuance of the corresponding FMVSS final rules, allowing NHTSA to delay NCAP adoption only if simultaneous issuance would delay rule completion. This sequencing is important because NCAP adoption changes consumer-facing ratings and can influence design incentives differently from regulatory compliance alone.
Congressional reporting on other devices and international comparators
Mandates an initial DOT report to the Senate Commerce Committee and House Energy and Commerce Committee within 1 year identifying timelines for incorporating other researched devices into parts 571/572, cataloguing more-advanced foreign testing devices, and describing a process for adopting those devices. A required five-year follow-up must report on progress and newly observed foreign advancements. This creates an explicit oversight loop for longer-term harmonization and modernization planning.
Savings provision
Clarifies that nothing in the Act restricts the Secretary from updating testing devices through other proceedings separate from (or after) the specific final rules and NCAP decisions the Act requires. It preserves regulatory flexibility while still imposing the statute’s deadlines.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Adult female vehicle occupants — The Act requires crash testing and injury criteria specifically calibrated to a 5th-percentile adult female dummy across front seating positions, increasing the likelihood that vehicle designs will better protect smaller female occupants.
- Crash-safety researchers and public-health analysts — New injury-criterion data and mandated use of female dummies will expand the empirical basis for studying sex and size differences in crash outcomes.
- Consumers using NCAP ratings — Bringing NCAP test procedures into alignment with sex-inclusive dummies will change ratings to reflect protection for a broader set of occupants, improving information for buyers concerned about occupant diversity.
Who Bears the Cost
- Automakers — Manufacturers will likely face engineering redesign costs, additional testing, and revalidation of restraint systems and airbags to meet new dummy criteria and seating-position requirements.
- Independent and in-house crash test labs — Labs must acquire, calibrate, and validate new THOR and WHSID dummies and instrumentation, invest in training, and potentially expand test capacity to meet faster timelines.
- Dummy and instrumentation suppliers — Demand will rise quickly, creating production and certification pressure; small suppliers may need to scale manufacturing and quality control.
- NHTSA and NCAP program staff — The agency must resource accelerated rulemakings, injury-criteria research, NCAP updates, and the two mandated reports, potentially requiring reallocation of staff or budget increases.
Key Issues
The Core Tension
The central dilemma is between quickly correcting a long-standing gap in protection for female and smaller occupants by imposing fast, statutory timetables versus the practical need for deliberate, technically rigorous rulemaking and validation. Speed advances occupant-equity goals but risks procedural delays, supply shortages, costly rework, or suboptimal choices if NHTSA and industry cannot properly validate and implement the new devices in the time allotted.
The Act enforces unusually tight statutory deadlines for complex rulemakings that typically involve extended technical rule development, notice-and-comment periods, test validation, and interagency coordination. Completing NPRMs and final rules for new anthropomorphic test devices on the 60–180 day windows the bill prescribes will require expedited protocols, early access to validated devices, and rapid data analysis; failure to meet procedural requirements under the Administrative Procedure Act could expose the rules to legal challenge.
The law also presumes availability of validated THOR and WHSID models, calibrated instrumentation, and lab capacity—assumptions that may not hold uniformly and could produce bottlenecks or uneven compliance costs.
Another practical tension arises from coupling NCAP adoption to FMVSS rule timing. NCAP changes are policy tools that shift market incentives through consumer ratings, while FMVSS updates set minimum safety requirements.
Tying NCAP to the same schedule as compliance rules risks either slowing a regulatory update to preserve consumer-score integrity or forcing NCAP to adopt devices before industry test practices stabilize. Finally, the push to align with international devices (via the roadmap) raises harmonization questions: adopting foreign devices can speed global conformity but may require U.S.-specific validation studies due to different fleet, lane, and seatbelt geometry patterns, and it could unintentionally favor vehicles engineered to perform on test dummies without guaranteeing commensurate real-world improvements across diverse occupant populations.
